# IALU code-path is optimized for elder Pentiums. On vanilla Pentium

# performance improvement over compiler generated code reaches ~60%,

# while on PIII - ~35%. On newer µ-archs improvement varies from 15%
|
|
# to 50%, but it's less important as they are expected to execute SSE2
|
|
# code-path, which is commonly ~2-3x faster [than compiler generated
|
|
# code]. SSE2 code-path is as fast as original sha512-sse2.pl, even
|
|
# though it does not use 128-bit operations. The latter means that
|
|
# SSE2-aware kernel is no longer required to execute the code. Another
|
|
# difference is that new code optimizes amount of writes, but at the
|
|
# cost of increased data cache "footprint" by 1/2KB.
